25.

If the value of n = 0 in the equation pvn = C, then the process is called

 [A]. constant volume process [B]. adiabatic process [C]. constant pressure process [D]. isothermal process

Explanation:

No answer description available for this question.

 Rajesh said: (Jul 17, 2013) p*1=c that is p=c hence the process is at constant pressure process.

 Balu said: (Aug 22, 2013) We know "v" to the power 0 is 1 so we get p = const.

 Sharad Ingle said: (Sep 23, 2013) When V=1 then P*1=C. And 0 power of anything=1.

 Amol Chaudhari said: (Jan 21, 2014) We know anything raise to 0 is 1 so v=1 and p*1=c i.e. p=c therefore constant pressure process.

 G Sudhakarreddy said: (Aug 23, 2014) When n=0, the equation may write as p=c. So pressure is constant.

 Gururaj said: (Jul 2, 2016) Its wrong, this is according to thermodynamics second law and einstein 2nd law.

 Govindaraj R said: (Sep 15, 2016) IT' S WRONG ("PV = MRT = C"{MEANS (CONSTANT TEMPERATURE PROCESS)).

 Hari said: (Nov 5, 2016) Isothermal process pv = c.

 Madai Nayagan said: (Nov 29, 2016) If anything to the power zero is value zero V power 0 is zero so P is equal to c (constant).

 Engr Arshad Jamali said: (Dec 9, 2016) If n=0 then p=C hence we can say that pressure constant process.

 Pradeep G said: (Jul 27, 2017) PVn = C polytropic process. PV = C isothermal process.

 Vilas said: (Sep 8, 2017) If n=1 what will happen?

 Narsingh said: (Oct 10, 2017) n=0,pv^0=constant.i .e.,isobaric process (p=const). n=1,pv=const.i.e., Isothermal process (temperature= const). n=gama,pv^gama=const.i.e., Isentropic process. n=infinity,pv^infinity=consnt.i.e.,v= const i.e, isochoric process (v= const).

 Paul said: (Aug 12, 2018) It should be isothermal process.

 Ausha.Ambati said: (Feb 10, 2019) When n is 0 in this equation then P is constant.

 Monika Jondani said: (Apr 17, 2019) n=0 Isobaric. n=1. Isothermal. n>1. Polytropic. n=gamm. Adiabatic. n=infitniy Constant volume.

 Yash said: (Jul 2, 2019) There are three basic processes: 1. pv^n = c is polytropic process. 2. pv^gamma=c is an adiabatic process. 3. pv=c is isothermal process.
